Travel by train
Travel by train I just returned from our vacation in Germany (and Prague). We traveled entirely by train, no plane nor flight. It was great!
Travel comfort: being able to just arrive at the station, minutes before departure, just enter the train, no security check, keep your luggage with you (that might be considered negative, but I like it). You then have more room, you are not confined to your square inches, walk around freely, Internet, charge your devices with real outlets…
